Smaller objects are too faint to observe except when they come very close and so most can only be observed on final approach. Collisions between galaxies, or galaxy mergers, have been observed directly by space telescopes such as Hubble and Spitzer. Archived from the original on Retrieved.

Instead, it was widely thought that cratering was the result of volcanism : the Barringer Crater, for example, was ascribed to a prehistoric volcanic explosion (not an unreasonable hypothesis, given that the volcanic San Francisco Peaks stand only 30 miles (48 km) to the west). It is now thought to be a remnant of the Lunar Prospector mission in 1998, and is the third time any previously unknown object natural or artificial was identified prior to impact.
